We divide 89536250 by 231
The aim is to understand the frequency of 231 in 89536250.

Advancing to step 1:
8 divided by 231 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 231

Going ahead to step 2:
When dividing 89 by 231, we get 0 with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Append the next digit (5) from the dividend to 89 and continue with: 895 / 231

Going ahead to step 3:
231 can be fit into 895 3 times, resulting in a remainder of 202.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 693 away from 895, we end up with 202.
Bring next digit (3) of the dividend behind the 202 and repeat the process: 2023 / 231

On to step 4:
231 goes into 2023 8 times with a remainder of 175.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
The remainder is 175 after subtracting 1848 from 2023.
Bring next digit (6) of the dividend behind the 175 and repeat the process: 1756 / 231

Advancing to step 5:
When dividing 1756 by 231, we get 7 with a remainder of 139.
The next digit of our result is 7. 
Result so far: 387.0
If we take 1617 away from 1756, we end up with 139.
Append the next digit (2) from the dividend to 139 and continue with: 1392 / 231

Step 6:
231 goes into 1392 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 3876.0
Subtracting 1386 from 1392 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 231

Moving on to step 7:
When dividing 65 by 231, we get 0 with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 38760.0
Subtract 0 from 65 to get 65.
Append the next digit (0) from the dividend to 65 and continue with: 650 / 231

Advancing to step 8:
231 can be fit into 650 2 times, resulting in a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 387602.0
Subtracting 462 from 650 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 9:
1880 divided by 231 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 387602.8
The remainder is 32 after subtracting 1848 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
If we divide 320 by 231, we get 1 and a remainder of 89.
The next digit of our result is 1. 
Result so far: 387602.81
The remainder is 89 after subtracting 231 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 11:
If we divide 890 by 231, we get 3 and a remainder of 197.
Write down 3 as next digit of the result. 
Result so far: 387602.813
If we subtract 693 from 890, we get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 12:
When dividing 1970 by 231, we get 8 with a remainder of 122.
Write down 8 as next digit of the result. 
Result so far: 387602.8138
Subtracting 1848 from 1970 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 13:
The number 231 fits into 1220 5 times, leaving a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 387602.81385
Subtract 1155 from 1220 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 14:
650 divided by 231 is 2 with a remainder of 188.
The next digit of our result is 2. 
Result so far: 387602.813852
Subtracting 462 from 650 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 15:
If we divide 1880 by 231, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 387602.8138528
Deduct 1848 from 1880 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 16:
When dividing 320 by 231, we get 1 with a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 387602.81385281
If we take 231 away from 320, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

The final result is 387602.81385281 with a remainder of 8.9e-08.
